    I have a neoprene neck seal and latex wrist seals and have no complaints. The same would probably be true for any other combination though.

    That seems a bit harsh. he's only trying to understand how things work; not telling everybody who replies that they're wrong.

    "Linearity" in this context describes the way that the cell output varies with respect to its input and specifically "how close is it to a line of constant gradient".

    A lot of the content you linked seemed to be discussing the idea that the calibration constants could somehow become lost or corrupted without anything else in the software being damaged.

    The underlined part is incorrect as 0.02 bars oxygen could also give essentially 0.000 Volts. Since with two known measurements you can calculate both the gain and DC offset there's no reason not to...

    To be honest, I'm still not getting it.

    How is knowing that a cell is reading 500mV instead of the exact same thing displayed as 1.2 bars going to help you detect current limiting? The problem is...

    P = a + bV

    Where the a and b coefficients are calculated during calibration at two known values...

    I don't want to sound like a duffer, but what do you mean by "mv"? The voltage reading in millivolts across the load resistor?

    I think that they pretty much all do. However, very much like the theoretical loss associated with a long hose, it doesn't seem to make any difference in practice.
